Usage and precautions of beer yeast in aquaculture

There are various ways to use beer yeast in aquaculture, and the following are some common methods and precautions:

usage method

Add to feed: Mix beer yeast powder with aquatic feed in a certain proportion and feed evenly. The addition ratio of different aquatic animals varies. The recommended dosage for conventional aquatic animals is 5% -10% of the feed, while the recommended dosage for special aquatic products such as shrimp, crab, eel, and marine fish farming is 5% -15%.

Making fermented feed: fermenting beer yeast with other feed ingredients to make fermented feed. During the fermentation process, beer yeast breaks down some nutrients in the feed, producing beneficial metabolites such as organic acids, vitamins, enzymes, etc., which improve the nutritional value and palatability of the feed, while also inhibiting the growth of harmful bacteria.

Water Splashing: Suspend beer yeast and evenly sprinkle it into the aquaculture water. This method can increase the number of beneficial microorganisms in water bodies, regulate water quality, promote the growth and reproduction of plankton, and provide natural feed for aquatic animals. But when sprinkling, attention should be paid to the dosage and uniformity to avoid excessive local concentration.

matters needing attention

Storage conditions: Beer yeast powder is prone to moisture absorption and clumping, and should be stored in a ventilated, dry, and cool place. It should not be mixed with toxic or harmful substances for storage. Unopened products should be used within their shelf life, and should be used up as soon as possible after opening. The unused parts should be sealed and stored.

Dosage: Strictly follow the recommended dosage and avoid excessive addition. Excessive use may lead to increased feed costs and may also have adverse effects on the growth and health of aquatic animals.

Stir evenly: When adding beer yeast to feed, make sure to stir evenly so that each feed contains beer yeast evenly to ensure a balanced nutrient intake for aquatic animals.

Observation reaction: After using beer yeast, closely observe the feeding, growth, and water quality changes of aquatic animals. If any abnormalities are found, the use should be stopped in a timely manner, the reasons should be analyzed, and corresponding measures should be taken.

Combination with other substances: Beer yeast should be used in conjunction with other feed additives, drugs, etc. Some substances may interact with beer yeast, affecting its effectiveness or causing adverse reactions. It is best to consult a professional before using multiple substances simultaneously.
